“We don't want to follow the crowd, we want to steer our own path into what we think are the most exciting opportunities for patients.” says Fiona Marshall, President of Biomedical Research at Novartis, joins Bloomberg Intelligence analyst Sam Fazeli to explain the biology-first, modality-second philosophy shaping R&D. Marshall details how Novartis is building radioligand therapy beyond Pluvicto into a broad portfolio across tumor types, while treating delivery as the bottleneck for expanding siRNA beyond the liver. The discussion also explores neuroscience as a growth bet built on earlier diagnosis and intervention, plus why AI productivity depends on embedding data scientists across the organization and training models on Novartis's proprietary data.
